ionic: link in the new hw timestamp code

These are changes to compile and link the new code, but no
new feature support is available or advertised yet.

ionic: add devlink firmware update

Add support for firmware update through the devlink interface.
This update copies the firmware object into the device, asks
the current firmware to install it, then asks the firmware to
select the new firmware for the next boot-up.

The install and select steps are launched as asynchronous
requests, which are then followed up with status request
commands. These status request commands will be answered with
an EAGAIN return value and will try again until the request
has completed or reached the timeout specified.

ionic: Add driver stats

Add in the detailed statistics for ethtool -S that the driver
keeps as it processes packets. Display of the additional
debug statistics can be enabled through the ethtool priv-flags
feature.

ionic: Add Tx and Rx handling

Add both the Tx and Rx queue setup and handling. The related
stats display comes later. Instead of using the generic napi
routines used by the slow-path commands, the Tx and Rx paths
are simplified and inlined in one file in order to get better
compiler optimizations.

ionic: Add initial ethtool support

Add in the basic ethtool callbacks for device information
and control.

ionic: Add management of rx filters

Set up the infrastructure for managing Rx filters. We can't ask the
hardware for what filters it has, so we keep a local list of filters
that we've pushed into the HW.

ionic: Add basic lif support

The LIF is the Logical Interface, which represents the external
connections. The NIC can multiplex many LIFs to a single port,
but in most setups, LIF0 is the primary control for the port.

ionic: Add hardware init and device commands

The ionic device has a small set of PCI registers, including a
device control and data space, and a large set of message
commands.

Also adds new DEVLINK_INFO_VERSION_GENERIC tags for
ASIC_ID, ASIC_REV, and FW.

ionic: Add basic framework for IONIC Network device driver

This patch adds a basic driver framework for the Pensando IONIC
network device. There is no functionality right now other than
the ability to load and unload.
